WILLIAM JEFFERSON CHANCE, OF DAWSON, YUKON TERRITORY, CANADA.

ELEVATED CARRIER.

Specification of Letters Patent. Patented May 5, 1908.

Application filed July 15, 1907. Serial No. 383,789.

To all whom it may concern: I

Be it known that 1, WILLIAM JEFFERSON or abutment block 2, having thedepending CHANCE, a citizen of the Dominion of Canada, latch portion orlug 3, at its forward end, and residing at Dawson, in the YukonTerritory the depending counter-weighted extension and Dominion ofCanada, have invented cerl 4, at its rear end, which serves to retainthe tain new and useful Improvements in Ele- I stop block in theproper'upright position. vated Carriers, of which the following is a Thecarrier frame consists of two side memspecification. bers 5, each membercomprising a top bar or My invention relates to improvements in rail 6,depending end bars 7, an intermediate elevated carriers, and has for itsobject the longer depending bar or plate 8, a short lower provision ofan aerial or overhead conveyor bar 9, connected between the rear end barsystem which will be automatic in its operaand the intermediate bar 8,and a diagonally tion, which will be of simple and durable conarrangedbar 10, extending from the rear end struction and which will bepractical and of the upper bar to the lower depending end efficientin'every particular. of the front bar. These two side members Anotherobject of my invention isthe proare secured together in spaced relationby the vision of an automatic hoisting and convey spreaders or spacingbolts 11, and by reason of the braced construction, the carrier frame islight, compact and very strong. Sheaves 12, are journaled in the upperends of the frame between the side members, which engage the cable ortrack and form the roller supports for the carrier.

load sheave 13, is journaled in the front lower end of the carrierframe, preferably at the juncture of the diagonal braces with the frontdepending braces 7, over which passes the hoisting rope or cable 14, thestationary end of the cable being anchored to the spreader or securingbolt 15.

The forward edge of the depending bar or plate 8. is rounded or curvedinwardly and upwardly as at 16, to form a guiding edge, and acomplementary guiding edge 17, is formed on the oppositely disposeddepending guide plate 18, the depending portions-of the two plates thusforming a gradually narrowing guiding passage. At the head of thisguiding passage between the guiding plates, is pivoted the tumbler 19,which is formed with a supporting hook extension 20, which when thetumbler is in the upright supporting position, extends across theopening between the guide plates. As shown in the drawings, one of thespreaders of the carrier frame may be utilized to serve as an abutment,to limit the lower movement of the tumbler. When the tumbler is in thislower or non-supporting position, the upper leg or portion 21, 0f thetumbler extends across the guiding opening.

A latch member 22, is pivoted at 23, in the rear portion of the frame,the upper portion of the latch having a jaw recess therein to engage thelug or tooth 3, on the end of the bumper. The movement of the latch isliming apparatus which may be adapted for a great variety of purposessuch as hay conveyers, excavating systems, for coaling ships at sea, andfor many other like uses.

With the above and other objects in view my invention consists of atrack or cableway, a carrier adapted to travel thereon, a hoistingsheave supported by the carrier, means for automatically locking thecarrier at predetermined points on the trackway, and automatic means forreleasing the hoisting sheave to lower the load at such predeterminedpoints. a

My invention further consists of an elevated carrier embodying certainother novel features of construction, combination and arrangement ofparts substantially as disclosed herein and as illustrated in theaccompanying drawings, in which:

Figure 1, is a side elevation of my improved tumbler carrier, with theparts shown in the release or nonsupporting position, the near side ofthe carrier frame being removed to more clearly illustrate the parts.Fig. 2, is a like view of the device with the parts in theload-supporting position. Fig. 3, is a verti cal sectional view takenthrough the carrier and sheave frame.

My invention is particularly adapted for use where the cable or track isplaced at an incline, as on the side of a hill for instance, and it isillustrated as such in the accompanying drawings. It will be understood,however that I do not limit myself to the use of an inclined trackway,as the invention may as well be adapted for a straight or irregular Inthe drawings: The numeral 1 designates the cable or track upon which atthe desired point is bolted or otherwise secured the stop ited by meansof the abutment or spreader tical and satisfactory tumbler carrier which24.

The weight on thesheave frame draws the tumbler down, the sheave frame then being free tofall to deposit the load in the proper place. A reverse procedure isgone through with in hoisting the load and carrying to a differentlocation.

From the foregoing description taken in connection with the drawings,the operation and advantages of my invention will be readily understoodand appreciated, and it will be apparent that I have provided a prac-Witnesses:
